SPECIFICATION forming part of Letters Patent No. 499,499, dated June 13,1893.

Application filed April 4, 1892. Serial No. 427,669. (No model.) I

To all whom it may concern:

Be it known that I, RICHARD T. BARTON, of New Haven, in the county ofNew Haven and State of Connecticut, have invented a new Improvement inLamp-Burners; and I do hereby declare the following, when taken inconnection with accompanying drawings and the letters of referencemarked thereon, to be a full, clear, and exact description of the same,and which said drawings constitute part of this specification, andrepresent, in-

Figure 1, a view in vertical central section of a lamp-burnerconstructed in accordance with my invention; Fig. 2, a similar Viewtaken at a right angle to the plane in which Fig. 1 is taken; Fig. 3, adetached view in side elevation of the wick-band and inner wicktube;Fig. 4, a broken view in transverse section showing the rack, the pinionand a section of the spindle of the wick -adjusting mechanism.

My invention relates to an improvement in that class of Argandlamp-burners which take the air in through the side of the inner wick ordraft-tube instead of through the lower end thereof, the object being toproduce at a comparatively low cost for manufacture, a simple,convenient and safe lamp-burner, not liable to derangement, andconstructed with particular reference to the avoidance of the ignitionof any oil which may accumulate in the inner wick-tube.

With these ends in view, my invention con sists in a lamp-burner havingcertain details of construction and combinations of parts as will behereinafter described and pointed out in the claims. I

The wick-band A of my improved lampburner is adapted to encircle theinner wicktube B, and is furnished with two horizontal series ofoutwardly projecting teeth a, which take into the wick, and with twolong depending arms A A located opposite each other, and perforated attheir lower ends to receive fingers c 0 formed upon the projecting endsof a Hat, sheet-metal yoke-shaped couplingplate C, located in a verticalplane within the inner wick-tube B, and having its bowed edge uppermost.To permit the described connection between the said wick-band andcouplingplate, the inner wick-tube is constructed with two long verticalslots b I) located opposite each other. By providing the wick band withlong arms, and by using a yoke-shaped coupling-plate with its bowed edgeuppermost, as set forth, I am enabled to locate the slots in the innerwick-tube through which the said wick-band and coupling-plate are.connected. so far below the upper end of the tube that any oiland fuzzwhich may work through them from the wick will not be in danger ofignition. A sheetmetal rack D, of U-shaped cross-section, is connectedat its upper end with the said coupling-plate and constructed with avertical series of transverse openings d, which adapt it to be takeninto by a pinion E, mounted on ahorizontal spindle F, the outer end ofwhich is furnished with a knurled button F, which is turned to raise andlower the wick. The pinion is entered into the concave face of the rack,the sides of which prevent it, and hence the spindle, from endwisedisplacement. The lower end of the rack passes downward through anopening B formed in the lower end of the inner wick-tube B, which isclosed except for the said opening. A racktube G, covering the saidopening B, depends from the said inner wick-tube, and receives the lowerend of the rack, its extreme lower end being furnished with avent-opening g. It will be observed that the coupling-plate by reason ofits form and arrangement, clears the said pinion, the plate beingmovable down over the same,whereby the range within which the rack, andhence the band, may be moved, is increased enabling a longer wick to beused than could otherwise be employed.

WVithin the upper end of the inner wicktube I locate a transverse bridgeH, which is arranged in a vertical plane at a right angle to the planeof the coupling-plate C. Thesaid plate is horizontally slit at itscenter, and struck up on opposite sides as at h, to form a centralvertical socket to receive the lower end of a post I, over which ispassed the sleeve J, of a disk-shaped deflector K, the lower end of thesaid sleeve resting upon the upper edge of the bridge H. The upper endof the inner tube is struck inward to form shoulders I) b situated inthe same horizontal plane, to afford supports for a small perforatedair-distributer L, located entirely within the upper end of the innerwick-tube, and having the form of a truncated cone, the upper end of thesaid distributer being enough larger in diameter than the diameter ofthe sleeve J, before mentioned, to permit a strong draft to pass upwardand impinge against the lower face of the distributer K. It will beobserved that the said deflector and distributer are entirelyindependent of the mechanism for raising and lowering the wick, and aretherefore not disturbed by the operation of the same. Air is admitted tothe inner wick-tube through a port B formed in its side, and receivingthe inner end of a short horizontal draft-tube M, the outer end of whichis entered into acorresponding port N formed in the side of the lowersection N of the outer wick-tube, the upper section N whereof rises tothe top of the inner wick tube before mentioned.

I am aware that it is old to furnish an Argand lamp-burner with awick-band encircling its innerwick-tube and connect the said band with aplate located within the said tube through long vertical openings formedtherein, that it is old to use a rack-tube to receive the projectinglower end of the rack of the wick-adjusting mechanism of such a burner,and also that it is old to support a deflector over the upper end of theinner wick-tube by means of a spindle rising from a bridge therein. I donot therefore claim any of those constructions broadly, but only myparticular construction and combination. I would'have it understood,however, that I do not limit myself to the exact construction andarrangement of parts herein shown and described, but hold myself atliberty to make such changes and alterations as fairly fall within thespirit and scope of my invention.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. In an Argand lamp-burner, the combination with an inner wick-tubeconstructed with two narrow vertical slots located opposite each other,of a wick-band encircling the said tube and having two long arms locatedopposite each other, a yoke-shaped coupling plate located in a verticalplane within the tube, with its bowed edge uppermost, and having itsends projected through the said slots and connected with the lower endsof the arms of the wick-band, and means for raising and lowering thesaid plate, substantially as set forth, and whereby oil and fuzz areprevented from entering the upper end of the said tube from the wick.

2. In an Argand lamp-burner, the combination with an inner wick-tubeconstructed with two narrow vertical slots located opposite each other,of a wick-band encircling the said tube and-having two long armslocatedopposite each other, and closed at its lower end except for a smallopening, a rack located within the said tube, a pinion taking into thesaid rack, a yoke-shaped coupling-plate located in a vertical planewithin the tube with its bowed edge uppermost, and having its :;endsprojected through. the said slots, and

connected with the lower ends of the arms of the wick-band, asheet-metal rack of U- shaped cross-section, connected at its upper endwith the said plate, and passing at its lower end'throughthe opening inthelower end of the tube, apinion taking into the said rack and enteringthe concave side thereof, and a spindle on which the said pinion ismounted, substantially as set forth.

3. In a lamp-burner, thecombination'with an inner wick-tube closed atits lower end but for a smallcentral perforation and constructed with aport in'its side, and with two narrow vertical slots located oppositeeach other, of an outer Wick-tube constructed with a corresponding'port,adraft-tube joining the said ports to form aclosed passage between thetwo tubes, a wick-band encircling the inner wick-tube, and having twolongdepending arms located opposite each other,,a-yokeshapedcoupling-plate located within the inner wick-tube, with itsbowed edgeuppermost, and having its ends projected through the said slots, andconnected with the lower ends of the arms of the said bandga sheetmetalrack of U'-shaped transverse section, connected at its upper end withthe said plate, and extending at its lower end through the small openingformed in the lower end of the inner wick-tube, a pinion taking into thesaid rack from the concave side thereof, a spindle on which the saidpinion is mounted, and a rack-tube depending from the lower end of theinner Wick-tube and receiving the lower end of'the rack, substantiallyas set forth.

In testimony whereof I have signed this specification in the presence oftwo subscribing witnesses.
